...talked to the guy who did the service to it.....well i told him that its still leaking gas, and the gas was off....he said it couldnt be needle and seat because gas was off, the he asked me if my track was picked, and i told him yes.....then he asked if i could see where its leaking....i told him engine bay is dry, i tilted it on its side, and it was leaking out underneath at the front portion of track, and he said pull the tank i bet the picks got to it....


and that may be right, because when i was ripping on it at my house theres a ditch and i gassed it it dug down alot and vibrated almost like track was rubbing on something, or as if the track were loose, but it isnt......and i parked it 5 minutes after that and the next morning is when i found the gas underneath......

not looking forward to what i might find when i take the tank off.....ill have pics of my process to come.

Ok....i gutted my sled today, and have never torn down a sled like this before.....I found a few issues.....could any of this have caused my leaking issue do you think?

1. the return line from the gas shut off...not the one that goes to tank...the one that goes down towards carbs had been resting on the recoil cord...the rubbing of the rope went through the plastic guard on the line and did wear enough on the gas line to cause a very very small leak....1 drip every 3 seconds. got a new line for that.








2. the two lines that go into the gas tank....well i popped out the grommets, and there was nothing past the grommets...and i did find that the gas didnt all leak out....when i looked and shook the sled it seemed like there was no gas, but there was.

i emptied all the gas out and shook the tank.....two lines and two little screen pieces with a spring ( i figure this is a type of fuel filter) were just bouncing around in the tank, not connected.....the lines that were inside the tank were banana peeled on each end...replaced those two lines.

these werent connected to the lines, just bobbing around in tank.





i also took out the needle and seats, and they look good, i took out the needle from the seats and nothing looks bad...but they are new....cleaned my carbs again as well... and readjusted the screws and now i know they both match....Star screw set to 2 1/8 turns since at 2 turns idle was high...and the small flathead screw both are at 1 1/8......now if this isnt the basline setting please let me know.

Also im trying to get the two grommets back into the tank, and i cannot for the life of me get them back in....tried lubing with oil and no go, they started getting beat up so i stopped trying to force them in....any tips for this?



and with my sled like this...its scary.....i dont like her being in shambles....but also tank has no damage to it...





Lastly i said i would show my reupholster job so here it is.....like i said this cost me only 7 bucks......did it myself with no heat gun.....my saddlebags cover most of the ripples so im happy with the outcome.

Use WD-40 on the grommets and then put the line adapters through after they are in place.

The pickup screens are weighted to keep them at the bottom of the tank and also have a check valve in them to prevent the gas from draining back from the pump/carbs.

Cut the lines diagonally into a point so they go through easier as well.

Yeah, you've got your hands full but she'll be a better sled for the effort. Sounds like you're doing a lot of guess work. Do you have a manual?

no i do not have a manuel, but i know cars/trucks like the back of my hand, i can do anything to those so i thought why not, the only way to learn something to me is to just do it, i taught myself everything i know about vehicles by just doing it, never had schooling, plus i have probably the best job you can get in my state making $20+/hr so if i mess something up ill bring it in and have it fixed, im just cheap so i do everything myself....


but its been in the negitives temp wise so i havent touched the sled since monday....for the hell of it this weekend im going to replace every gas line, rebuild fuel pumps, and get new jets for the hell of it since its all apart, plus clean oil tank and put new oil in....already took over chaincase cover cleaned and put new fluid in, so hopefully after this i wont have to touch it again for a while.....


BUT i did find that the support arm that goes to the steering shaft on the left side is broke in two, clean break, my buddy has a welder so im not to worried about it, but i guess thats why i can move my handle bars up and down...

plus i also found a 91 mach 1 617cc in decent shape with a blown motor for $250....might have to go pick it up for parts cuz track is new on it, and my track has 5 (that ive found) picks that have ripped through

Re: 91 Mach 1 617cc bog issue

My ski doo had the same problem with almost dumping all the fuel on the ground after a day of farting around the yard. After 3 days of ripping my hair out I realized the breather tube for the gas tank had sealed itself shut. Recut it open and rerouted it; havent had puddling since.

well replaced pretty much all fuel lines, except breather lines, and got it all back together today....hasnt run in about 2 weeks, i primed it until i finally saw fuel since i emptied tank etc. and she started up first pull but once again very high idle....messed with both screws going in and out, and nothing will make the idle come down, it will go up more, but i cant keep it down, and now, when i turn right it holds the throttle, so it will keep moving unless i feather it to bring idle back to the point where the clutch about engages (high idle im saying)

im stumped, and i just quit smoking so im getting angry very easily and if i cant figure this out, the sled will die...i will beat the hell out of it until it dies....

Problem is likely that the throttle cables are too tight. if it revs up when you turn right, it's pulling on the cables.

Check the adjustment.

Try this,adjust your carb slides (idle adjustment) so that a 1/4 drill bit JUST slides under the center of your slides(exactly the same).Shoul b around 1800 rpm.While pulling the throttle open and closed make sure they open at exactly the same time(a mirror works best) if not loosen nut and adjust cable at carb...repeat as needed.

well i tried this, and made the idle worse, it made it so idle was so high it was engauging clutch...

tuned them down, and still idle is high, it wont come down.

AND on top of that i went ice fishing by myself today, had my sled out with me, and she ran fine aside from high idle...well i get to where im fishing, set up my traps, and i noticed me sled is pissin out all the gas i just put in it....shut gas off, and she still is leaking.....my tank is fine, and i have all new fuel lines, and all are still connected, its leaking where the track rounds about in the front, cant pinpoint where its leaking.....

getting real tired of this damn sled.....

im about to light a stick of dynamite and drop it in my gas tank.

finally got idle down a bit, but now when you go WOT it bogs out and shuts down.....cant find a happy median on this thing.....if i adjust anymore idle is going to be to high, or the other way its to low.......but i need this thing fixed...supposed to get like 2 feet of snow tomorrow and i want to ride

You have a big air leak somewhere,crank seal,carb boots,etc.If you ride this weekend youll need a new piston too.

well im kind of hard with thinking thats the case, i know my carb boots check out fine, but before i took carbs apart and messed with all the settings, thats when it started running like this....ran great before except for the bog like ive stated, and the new needle and seats/gas lines fixed that problem but the idle has been the problem now, if i feather it and when it builds up momentum you can hold it wide open and it goes.....but i did notice that on the carb near the clutches one of the vent lines was pouring out gas then it stopped, and hasnt done it since....leaked steady for about 30 seconds then stopped.



im going to double check the slides tomorrow and make sure they are synced right....messing with that is what brought my idle down.....could those being not in sync cause this problem?

.......................well

so i got the idle down and running good, no bog or skipping, slides match and both screws match on both carbs...while it was running i sprayed carb boots and crank seal areas with carb cleaner and there was absolutly no change to the idle. idle stayed good, so i think i can rule out a air leak since i can also hit it wide open and it doesnt stall out, she grabs and goes.....it was the throttle cables that was giving me all this headache.

well we have the snow hitting us now, and we are expected to get about 2 more feet by tomorrow....well i was trying to get the sled all put back together so shes ready to ride tomorrow but of course, something has to happen...i lost one of the nuts to the gas tank strap.....went to two hardware stores, matched the stock nut up to a bolt, then bought the nut for that bolt that the stock nut would thread to, and none of the nuts i got would thread down onto the post.....So all i have to do is get that one nut, and put the seat on then she will be 100% but of course this had to happen.....not pleased, so instead of riding in the morning, i have to go find a &%%$&%$ {+)%&* nut for this thing...
